Summary
This 2021 systematic review examines the range of flood hazard mapping methods used in hydrology and water resources management. The paper categorises and evaluates approaches—including hydrodynamic modelling, empirical methods, and probabilistic techniques—assessing their respective strengths, limitations, and suitability for different geographical and institutional contexts. As a methodological synthesis, it provides practitioners with evidence-grounded guidance for selecting appropriate flood risk assessment methods.
UK applicability
UK flood risk management and planning authorities routinely employ hazard mapping methods for coastal, fluvial, and surface water flooding. This review's categorisation of methodologies and guidance on method selection would be directly applicable to UK Environment Agency practice, local authority flood risk assessment, and climate adaptation planning under changing precipitation patterns.
Key measures
Comparative assessment of flood mapping methodologies (hydrodynamic modelling, empirical methods, probabilistic techniques, and related approaches); evaluation criteria for method selection and applicability
Outcomes reported
The study synthesises and categorises flood hazard mapping methods employed in hydrology and water resources management. It evaluates the relative strengths, limitations, and contextual suitability of different methodological approaches to flood risk assessment.
